查询词典 pingos

The local factors such as topography, vegetations and soil moisture contents, have great influences on the distribution, ground temperatures, and ground ice contents of permafrost. About 50 km of wetlands have been identified along the China-Russia crude oil pipeline route. In these segments, the surficial deposits consist of peat and humic layers on the top of thick ground-ice, or ice-rich permafrost. The frozen ground engineering geology conditions in wetlands generally are the worst for building and operating the pipeline. The hazardous periglacial processes, such as the widespreadpresence of pingos, icings and frost mounds due to the extensive occurrence of the frost-susceptible soils and ample supplies of surface and ground waters in winter pose significant threats on pipeline operation.

地形地貌单元、植被分布、地表水分条件的变化等局部因素对多年冻土的分布和地下冰的赋存产生重要的影响，管道沿线大约分布有50 km左右的沼泽湿地，其表层为腐殖质土及泥炭层，泥炭层下面分布着含土冰层或地下冰，是管道沿线最差的冻土工程地质地段；由于中俄原油管道沿线水系发育多，冻胀丘、冰椎和冰幔等不良冻土现象广泛分布。

Migrating pingos formed along fault zone in permafrost north Tibetan Plateau,destructing bridge,culvert and oil pipeline.

青藏高原北部常年冻土区断裂破碎带发育的移动冰丘对桥梁、涵洞、输油管道等工程设施具有不同形式的破坏作用。

Here displacement and stress fields caused by migrating pingos and stresses of bended bridge pier were calculated by three dimensional finite element modeling based on field observation and laboratory tests, and breaking mechanism of bridge pier was analyzed after the numerical modeling.

考虑移动冰丘与工程设施的相互作用，根据野外观测和实验资料设计模型，应用三维有限元数值模拟方法，计算移动冰丘冻胀产生的位移场、应力场和桥墩弯曲应力，分析桥墩破裂机理。

Hazards of Budongquan migrating pingos can be decreased or protected by taking engineering measures as building underground water conduits or draining off the upward rushing spring water near ground surface.

采用适当的工程措施，通过地下疏导或地表排放沿断裂破碎带上涌的地下泉水，能够有效减轻或防治不冻泉移动冰丘的灾害效应。

There are six typical migrating pingo s along the Qinghai-Tibet Railway and freezing and swelling of some of these pingos caused fracturing of bridge piers and culverts and bending of oil pipelines along the railway and highway.

青藏铁路沿线发育6个典型移动冰丘，冰丘冻胀对线路工程具有严重破坏作用，导致桥墩扭裂、涵洞破裂与输油管道弯曲变形，产生显著的灾害效应。

And scale, height and covering area of Budongquan migrating pingos further increased in 2006. Budongquan migrating pingos not only piered and etched the highway, but also destructed the culvert, depressed ground surface, bended oil-pipeline and formed ground fracture zones.

不冻泉移动冰丘不仅穿刺青藏公路路基，破坏青藏公路桥涵结构，蚕食青藏公路路堤，影响青藏公路的交通安全；而且导致输油管道拱曲变形，诱发地面塌陷和地裂缝，产生显著的灾害效应。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
